This cute song is a parody of "I Kissed a Girl" by Katy Perry. A sample of the lyrics:

I kissed a nerd and I liked itThe taste of his acne-chapped lipsI kissed a nerd, can't describe itI told my boyfriend to hike itTaped-glasses onPlaid pants so tightI think I'm in love tonightI kissed a nerd and I liked itI liked it
